Good explanation (from one physics nerd to another)!
MOND has always been really fascinating. What if we've just been wrong all this time about a fundamental way we interpret data? I mean, it happens all the time. But of course, MOND has almost died out by this time and WIMPs are the order of the day.
Great article. Got me more curious about dark matter.
